The page at the back was filled with every word Dazai had painstakingly written down when he first got the book.

Dazai Osamu read it word by word. After a while, he closed the "book" and let out a long sigh.

Now he can be sure that his counterpart is Dazai Osamu who owns this "book".

——His goal in coming here is to save his world.

"Save the world."

When this thought comes out and many words with a Chuichi flavor are associated with "Dazai Osamu", perhaps some people will involuntarily think that this is the fact.

But when it was Dazai himself, or his counterpart, who saw this, Dazai Osamu just wanted to laugh.

What an international joke.

Dazai Osamu? Save the world?

The young man with iris eyes suddenly laughed, and laughed like a madman, until tears came out of the corners of his eyes.

Only then did he slowly stop and wipe away the tears from the corners of his eyes.

Staring at Nakahara Chuuya's stupid look and Sakaguchi Ango's puzzled look, he reached out and gave the "book" to Sakaguchi Ango.

"Try using your special ability." Dazai said.

Sakaguchi Ango took over and subconsciously activated his special ability. Now when he heard Dazai Osamu's voice, he didn't react at all.

He is now immersed in the memories left in this "book".

He even saw images from another world.

——

It was first obtained by Ranpo Edogawa, who kept it to himself for a while, and finally went to find Dazai Osamu when Morio once again attempted to break through his parents' protection zone.

Then, at Dazai Osamu's instigation, he took a pen and wrote the words on the "book".

"Mom and Dad are still alive."

Ranpo Edogawa traded his health for a pair of fake parents, and soon after, he killed someone because the counterfeit was too inferior.

Afterwards, the "book" was handed over to Dazai Osamu by Edogawa Ranpo.

It wasn’t because he thought he couldn’t protect the “book”—or maybe that was the reason, Edogawa Ranpo held the book and said, “For your pity!”

Before this, Dazai Osamu had also come into contact with the "book", from which he obtained his own memories of the next world and derived an idea from it.

——He wants to save Oda Sakunosuke.

But as with Ranpo Edogawa's previous experience, they both realized that the "books" here are not the "books" of another world.

The "books" here can fulfill unreasonable wishes - provided that you pay enough.

Moreover, the form of completion is uncertain.

What Dazai Osamu wanted was the real Oda Sakunosuke, not a fake one.

Moreover, unlike Edogawa Ranpo, the death of Oda Sakunosuke belongs to the "future" for them.

In this case, Dazai Osamu can also save the real Oda Sakunosuke by "completing a reasonable world line".

After knowing this, he began to think about how to take the "book" from Ranpo Edogawa.

"Anyway...you need this more than Ranpo-sama." Ranpo Edogawa said casually while sitting on the sofa in Dazai Osamu's office holding his cake.

So, Dazai Osamu began his four and a half year plan.

During this time, Ranpo Edogawa would occasionally help him.

Dazai Osamu once said to Edogawa Ranpo, "The cost of changing the future is almost nothing. Our world is too ordinary. Everything can be developed in a different way from other places."
